Did you download it from our website or a software disk? If the software disk, what version please?
i experienced the same problem as soon as i download updates inside Parts Finder
Seems like it downloads invalid .ipb files into the folder C:\ProgramData\Agilent IPB Files
which contain an additional newline at the begining of the file..
Deleting the additionally downloaded files or removing the newline in them resolves the problem..
I have notified the developers of Parts Finder about this problem and hopefully it should be fixed soon.
